Motorola Suspends Powerline LV BPL Development:
Less than two years after announcing its Powerline LV Access BPL product,
Motorola has decided to suspend product development and to devote its
resources to more promising markets, industry sources say. Motorola
reportedly has decided to focus on a product called Powerline MU, which is
for use within multiple-unit dwellings. The decision to stop work on its
Access BPL product reflects declining interest in residential broadband
service delivery among utilities coupled with more immediate demand for
in-building BPL systems. Motorola has indicated that it's not scrapping
Powerline LV altogether, however.
Powerline LV united Motorola's Canopy wireless broadband Internet platform
with enhanced ham band-notching HomePlug technology, drastically reducing
BPL interference potential by restricting the application of high-frequency
RF to the low-voltage side of the power transformers serving customers'
homes, not the medium-voltage wires that line many residential streets. As a
result, Powerline LV avoided the system architecture that poses the greatest
risk of BPL interference to radio communication -- radiation from the
medium-voltage power lines.
ARRL Chief Executive Officer David Sumner, K1ZZ, expressed appreciation for
Motorola's approach to the thorny issue of radio interference from BPL
systems. In an effort to minimize interference, particularly to the Amateur
Radio bands, Motorola designed its Powerline LV system in close cooperation
with the League's technical staff, Sumner noted. A test stand Access BPL
system was in operation briefly at ARRL Headquarters. Measurements and
subjective listening tests on the ham bands showed that Powerline LV was
Amateur Radio-friendly.
"As one would expect from a company with such a distinguished record in the
field of radio communication, Motorola acknowledged at the outset the
seriousness of the interference problem," he said. "Motorola's system
architecture influenced other vendors, raised industry awareness of the
interference issue, and demonstrated the value of working with the ARRL to
find positive solutions."

A very interesting development in BPL which would seem to indicate that Utilities arer not embracing BPL, at least Motorola's solution. If this is an indicator of the overall attitude by the industry this could be big and very encouraging news for Amateur Radio. If the disinterest is unique to Motorola's Product then it could be very omnious sign as it would signal the industry is opting for Comtek's Cheap and Dirt Solution.
Let's hope the ARRL proceeeds full steam with it's Legal Action against the FCC's Ruling until BPL is dead and buried.

"Let's hope the ARRL proceeeds full steam with it's Legal Action against the FCC's Ruling until BPL is dead and buried."
The League has a new priority per recent announcements: regulation by bandwidth for the HF bands. That's where all the resources seem to be going. The League has gone repeatedly hat-in-hand to the FCC for support for the regulation by bandwith idea.
It's counterproductive then to keep crying foul over the Commission's broadband initiatives. Even for the gymnasts at Harrison, Sumner & Co., it's hard to keep doing back flips.

Economics is the only thing that will kill BPL;if it won't make money for the utilities it will be closed down.If BPL really could deliver reliable and cheap internet service to the nation's people then amateur radio would be reminded of the public interest,convenience,and necessity rule.

KC9OD is right.
ONLY economics can kill BPL. Not arrl. Motorola must have done a market assessment which showed unfavorable results for "overhead" BPL systems. Let us hope that when it comes to in-building systems, WiFi is more economical.
arrl's litigation is likely to fail.
Fortunately for us, we have a FAR MORE potent factor on our side. ECONOMICS.

Not really when you consider that bpl issues and internal ham radio issues and proposals are handled by different bureaus within the FCC.
